Fix various compiler warnings. Fix bug causing double free when a file isn't found. Fix bug using uninitialized variable parsing null filename. Fix bug causing crash when format 3 retrieval pointer encountered. Add support for readline (command line editing and history on Unix) Untangle NT I/O so it builds without the direct access SCSI API & works. Report errors as text messages everywhere. Add MSVC project files. Implement most of dir/full Partially implement XABITM Add help to command tables. Allow choice of VMS qualifiers or Unix options. mount /write // /dev/cdrom or mount -write /dev/cdrom Parse quoted strings as command parameters. Mount /write "/dev/cdrom" search [*...]*.txt "My words for you" Resolve command, parameter & qualifier ambiguity from tables. Consolidate the various makefiles into a common file with very small platform-specific wrappers. This simplifies maintenance. Add diskio module to allow easy access to .iso images and simulator files. Removes requirement for loop device or equivalent. Builds as a separate executable. Writes to the ODS2 volumes are broken.

/* To set up physical I/O for a new system a group of phyio
|
|
routines need to be set up. They are:-
|
|
phyio_show() which doesn't need to do anything - but
|
|
it would generally print some statistics
|
|
about the other phyio calls.
|
|
phyio_init() to prepare a device for use by future
|
|
read/write calls. The device name would usually
|
|
map to a local device - for example rra: to /dev/rra
|
|
on a Unix system. The call needs to return a handle
|
|
(channel, file handle, reference number...) for
|
|
future reference, and optionally some device
|
|
information.
|
|
phyio_read() will return a specified number of bytes into a
|
|
buffer from the start of a 512 byte block on the
|
|
device referred to by the handle.
|
|
phyio_write() will write a number of bytes out to a 512 byte block
|
|
address on a device.
